CAR-COULING MECHANISM.

Specification of Letters Patent.

Patented J an. 28, 1913.

To all whom 1' i may concern- Be it known that I, Euxss'r H. Sotnno'r, acitizen of the United States, and a resident of Cleveland, Cuyahogacounty, Ohio,-have invented a newand useful Car-Coupler Mechanism, ofwhich the following is a fuli, clear, and exact description, referencebeing had to the accompanying drawings forming part of thisspecification, in which Figure 1 is a plan view of one form of couplermechanism embodying my inven tion; Fig. 2 is a side view of the same;Fig. 3 is a detail sectional view taken on the line III-III of Fig. 1.

My invention hasrelation to car coupler mechanism, and is designed toprovide means for the installation and use of automatic couplers of theM. C. B. type upon cars which must be coupled not only with other M. C.B. couplers, but also with other types of couplers well known instreetrailway practice, such for instance as the Van Dorn coupler.

A further object of the inventionis to provide anautomatic coupler ofthe M. C. B.

type with a supplemental coupling device adapted to another form ofcoupler, and which can be readily attached to, or detached from theautomatic coupler or otherwise brought into and out of operativeposition.

The nature of my invention will be best understood by reference to theaccompany ing drawings, in which I have shown the preferred embodimentthereof, and which will now be described. it being premised, however,that various changes can be made in the form, construction andarrangement of the several parts by those skilled in the art withoutdeparting from the spirit and scope of my invention as defined in theappended claims.

In these drawings the numeral 2 dcsignates a coupler head of the M. C.B. type and having the pivoted knuckle 3. The coupler illustrated in thedrawing is of a well-knownbottom-opening type. having a lock-liftingmember 4. an actuating lever therefor. and any suitable uncoupling rodconnection with said lever. such as illustratcd in dotted lines in Fig.2. The -c parts. however. form no part of the present invention. andbeing well known in the art. need not be further described.

t3 designates the supplemental or emergency coupling member or link.'ihis incinknuckle 3.

which pivotally connects said member to the.

guard arm 9 of the coupler, said guard arm.

being slotted as shown at 10 to receive said arm 7. The pin 8 extendsobliquely rearwardly and downwardly for the purpose hereinafterdescribed. At its central portion, the member or link 6 has a socket portion 11 which is adapted to fit closely around the convex nose end 3* ofthe pivoted This socket portion 11 is extended in a vertical direction,as will be seen by reference to Figs/2 and 3 so as to afford a broadbearing surface. against the rounded end and nose of the knuckle.Extendingtransversely across this socket is a rib or web 12 which givesadditional strength to the member in pullin", the

knuckle being slotted at l3 to receive this rib or well in a mannersimilar to the slot ting of knuckles which was commonly employed whenthe old link and pin drawbars were in use. \Vhen the knuckle is in itslocked position, as shown in Fig. 1, the sup plemental or emergencycoupling member or link is held rigidly by means of its socketengagement withthe coupler and its pivotal connection to the guard arm,so that it becomes virtually a part of the coupler.

The forward end of the member or link 6 is provided with a hook or otherhead por tion 6, which is adapted to couple with the couplers of cars ofother than the automatic type. \Vhen it is desired to /remove theemergency member or link so as to give access to the coupler forautomatic. coupling, thecoupler lock is released in the usual mair ncr,thereby releasing the knuckle 3 and permitting the member 6 to be swungrearwardly about its pivot pin 8. into the position shown. in dottedlines in Figs. 1 and 2. lhe rearward lnclination o1 this pin. beforereferred to. causes the outer end of the mem her to rise and clear thecoupler shank over which it passes. When it has been swung rcarwardly asfar as its shape. will permit, a lockingdevice ll is swung forwardly infront of the notch 7, thereby holding said member securely out of theway until it is again l'rtfltil'ttl to! l l. t. In the particular formshown. the lock 14 consists of a strip oi nn-tal bent into triangularform and rotatabl pivoted at 13 to a bracket 16 which is se ured to thecoupler shank.

The advantages of my invention will be readily understood, since itprovides simple and practical means whereby street railway cars whichare required to be coupled with. cars having couplers of other than theautomatic type may, nevertheless, be provided with automatic couplersand coupled with other cars having couplers of either type.

It will be readily understood that the form of the supplemental oremergency coupling'memberor link may be changed in various ways, andthat it may be fitted and secured to the automatic coupler by differentmeans than those shown.

What I claim is 1. In coupler mechanism, the combination with anautomatic coupler having a pivoted knuckle,-of a supplemental couplingmember pivoted to theguard arm of the coupler head, and adapted" to beswung backwardly over the shank ieithe coupler; substantially asdescribed; y

2. In couplermechanism, the combination with a coupler of the automatic.type-having a pivoted knuckle, of a supplemental cou-i 25 pling memberpivoted to the guard arm of the automatic coupler and adapted to beswung backwardly over the shank of the coupler, the pivotal connectionhaving a rearwardly and downwardly inclined axis; substantially asdescribed.

3. In coupler mechanism, the combination with a coupler of the automatictype, of a supplemental coupling device pivoted there to and adapted tobe swun backwardly over the shank of the coupler w en not in use,together with a locking device for retaining the supplemental member insuch position; substantially as described.

In testimony whereof, I have hereunto 'set 40 my hand.
